node.name: Node. 1-
bootstrap.memory_lock: to false
network.host: 10.100.2.235
http.port,: 9200
discovery.zen.ping.unicast.hosts: [ "10.100.2.235"]
discovery.zen.minimum_master_nodes: 1 # Note that, because the current I is a single node, there must be 1
3) added as follows:
transport.tcp.port: 9300
transport.tcp.compress: to true
bootstrap.system_call_filter: to false

# esuser for the user login name server
esuser Soft nofile 65536
esuser Hard 65536 nofile
esuser Soft nproc 4096
esuser Hard nproc 4096

1) The user switches
SU esuser
2) the user to view the current
WHO I AM
